Resumen

Gas transport properties of rubbery cross-linked poly(ethylene oxide) films containing short phenoxy-terminated pendant chains are reported. Poly(ethylene glycol) diacrylate (PEGDA) was UV-polymerized with poly(ethylene glycol) phenyl ether acrylate co-monomers of two different ethylene oxide repeat unit lengths: n = 2 (DEGPEA) and n = 4 (PEGPEA). Although fractional free volume increased with increasing co-monomer concentration, gas permeability did not rise accordingly. For instance, while FFV increased from 0.120 to 0.135 in both series of copolymers, CO₂ permeability went from 110 to 35 barrer (DEGPEA) or to 100 barrer (PEGPEA). At the same time, glass transition temperature increased from -37 to -12 °C (DEGPEA) or to -28 °C (PEGPEA). The observed decrease in chain mobility with phenoxy-terminated co-monomer content indicated by increasing glass-rubber transition temperature apparently had a stronger influence on gas transport properties than the increase in fractional free volume.
